WebBromine is the only non-metallic element that is liquid at room temperature and standard pressure. It is a red liquid that easily evaporates and smells. Bromine is approximately 3,12 times heavier than water. At temperatures of 58,8 °C it becomes gaseous, whereas at –7,3 °C and lower temperatures it is a solid. Bromine is a bleach. http://commonorganicchemistry.com/Common_Reagents/Sodium_Bisulfite/Sodium_Bisulfite.htm

An important example is salt formation with acids and bases. Alcohols, like water, are both weak bases and weak acids. The acid ionization constant (Ka) of ethanol is about 10~18 ...
Webhypobromous acid. For these reasons bromine is effective for applications such as microbiological control in cooling towers with pH in the 7.5 to 9.0 region. pH is an important variable in bromine-water systems, since it determines what form the bromine takes. When bromine liquid is added to water, it hydrolyzes rapidly according to equation 1.
